Correct. That procedure resets the camera back to the factory default settings, removing all user settings, including network configuration, user name, password, etc.
There are a number of things I would have tried and looked at prior to performing the factory reset procedure, but it looks like it's too late to cross that bridge.
Please post back when you have physical access to the camera.
In the interim, I'm moving this post to the DCS-2330L board. . . unless this is regarding multiple cameras -- you mention that "The first is the DCS 2330L". Is there another camera? Is this camera experiencing the same issue?
